TIRETIGHTENER.

SPECIFICATION forming part of Letters Patent No. 721,033, dated February 17, 1903.

Applioationiiled June 18l 1902.

To @ZZ whom it may concern:

Beit known that I, OLIN R. GOULD, a citizen of the United States, and a resident of Y Marionyin the countyof Linn and State of Iowa, have made certain new and useful Im-v provennentsv in Tire-Tighteners, of which the. following is a speciiication.

My invention'is an improvement in tiretighteners, and has for Van object, among others, to provide a simple construction whereby the felly can be tightened within the tire by spreading the telly-sections; and theV invention consists'in certain novel constructions and combinations of parts, as will be hereinafter described and claimed.

In the drawings, Figure l is a perspective view of my invention as in use, and Fig. 2 is a detail perspective view. showing the improved tire-tightening device removed from the wheel'. Fig. 3 is a. detail sectional elevation through the operating. device, and Fig. liis a detail perspective view of the tightene'r as 1n use.

By my invention I provideV an improved tightening device which can be applied to the wheel to operate upon the spokes to spread the felly and provide an opening between adjacent ends of the felly-sections, as shown in Fig. l, which can be lled to tighten the wheel*Y within the Lire. Y

In the construction shown I employ screws A and B, head-plates a and b at the outer ends thereof, bearing-frames O and an intermediate supporting-frame D, a lever, E and nut-sections F, having gear-wheels f, engaged by the pawl G on the leverE, the nut-sections F being journaled to the main frame D, and the latter beingesecured to a spoke l, intermediate the spokes 2,A to which the bearingframes C are applied. The bearing-frames C are of a special construction and consist each of the two opposite side plates C', connected by the inner and outerV bolts C2 and C3 and'lapping at their sides slightly along the spokes 2 and at their outer ends on opposite sides of the rim of the wheel, as shown at C4 in Fig. 1. The plates C are provided comparatively near the outer bolts C2 with inclined surfaces C5, and each of the headplates a and b is applied in the operation of Serial No. 112,130. (No model.)

operating to press the bearing-frames C apart 'and so spread the felly-joint at 3, as shown in Fig; 1. l Y

The main frame D is applied to the spoke 1 and secured thereon as shown. It isprelfel-red to make the frame D in sections tting ,on opposite sides of the spoke 1 and secured, as thereby I provide a rm anchorage and support for the lever, the nuts, and the bolts, as will be understood from Fig. l. In the operation of the device the bearingplates u, and b may be drawn Atoward each other by the operation of the lever and the frames Cbe applied to the spokes 2, the frame VD applied to the spoke l, and the parts adjusted and operated tothe position shown in Fig. 1, thusspreading the wheel-rim, and open- Aing one of the joints, which may be iilled as desired.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is- Y v l. The tire-tightener herein described-consisting of the bearing-frames' havingY the opposite side plates and the bolts connecting the saine and constructed at their outer sides to overlap the spokes and at-their outer ends to overlap the rim of the wheel and having such side plates provided with inclined snrfaces forming seats for the head-plateso the bolts, the bolts or screws and their `lieadplates, theV nut-sections and the lever and paWl-and-gear mechanism for operating the same, and the main frame arranged intermediate the bearing-frames, substantially as and for the purposes set for-th. 1 1 2. Atire-tightener comprisingamain frame, theopposite bearingframes', the opposite screws, the nuts operating upon said screws and having ratchet-wheels on opposite sides of the main frame, and the lever provided on opposite sides of the main frame withgpawls engaged with their respective ratchet-wheels substantially as set forth. l y
